LAMPS AND LAMP-TORCHES.

Specification of Letters Patent No. 248, dated June 30, 1837.

To all whom it may concern:

Be it known that I, JEREMIAH MARTIN, of Boston, in the county of Suffolk and State of Massachusetts, in the United States of America, have invented a new and useful Improvement in Lamps and Lamp- Torches, of which the following is a true and exact description.

The object of thisimprovement is to furnish a receptacle cup or space, to intercept and contain the oil or other combustible fluid that lea-ks or flows from the bowl or reservoir of the lamp, or lamp-torch 'in case of the oil or other fluid flowing out at the top through any aperture or orifice by reasonof the expansion of the oil or other fluid by heat or by reason of the reservoir being filled so full as not to have suflicient room for the stoppers or screw at tached to the burner or by reason of the. lam being placed in an oblique position when full or nearly so. For this purpose a. cup or rim is formed around the burner on the part of the lamp or lamp-torch Where the burner is inserted-into, or screwed into, or upon the lamp or lamp torch. This cup or rim is not attached to the burner or its appendages but is attached to or formedupon the bowl or body of the lamp or lamptorch, at the part where the burner isin serted, and surrounds and incloses the burner. The form of this receptacle for the oil or other fiuiol that leaps or gushes from the burner, or from the place of its inser tion, may be conical or semiglobular, or cylindrical havingan opening at the top for the burner, or it may be of a diiferent form from these the construction being such in all cases that the sides of the receptacle do not intercept the light of the lamp. The interior form of the receptacle should be such, that on the subsiding of the oil or other fluid within the lamp reservoir, the excluded oil or other fluid may run back into the reservoir or pass to the wick to supply combustion. The form of a hollow semicylinder bent circularly around the burner feeding the wickwith it, and alsofor being 7 cleaned.

p The annexed drawing is referred to in illustratlon and explanation of this specification.

The inventor claims as his invention The said'improvement as above described for the purposes above set forth.

In witness whereof I the said JEREMIAH MARTIN, hereto subscribe my name this first day of Feby A. D. eighteen hundred and thirty seven.
